The Potential for Conservation Tillage Adoption in the San Joaquin Valley, California

Book Description
While California researchers and relatively few farmers have successfully proven the efficacy of conservation tillage (CT) in the region, the adoption of the practice in the San Joaquin Valley (SJV) remains low. The gap between successful integration of these practices on farms and widespread adoption highlights the need to study the barriers limiting adoption. A combination of survey and interview methods was used to characterize CT adopters and non-adopters in the SJV and to learn directly from farmers about the barriers to CT adoption and the process of adoption used by current CT farmers. The survey quantified responses from 304 farmers about their attitudes toward CT, and the interviews collected more in depth information from 9 SJV farmers representing adopters and non-adopters. Larger farms with less crop diversity had higher levels of CT adoption which is of importance in the Central Valley region known for its diverse vegetable cropping rotations. Farmers who are not using CT indicated that "CT won't work for [their] crops" and that the economics had not yet been proven for this region. Survey and interview based insight from farmers already using CT suggests that, like many agricultural innovations, CT requires a commitment to gaining the knowledge and direct experience required to make it work. An additional and unexpected finding of this work is that farmers have different definitions of conservation tillage. Not only do farmers have different CT definitions but the farmers who have adopted CT have had to adapt CT systems that address challenges unique to their farms. Based on the findings of this work, extension efforts to increase adoption of CT will be most successful if they make clear the various challenges that can arise during CT adoption and offer continued support and assistance for farmers to develop their CT system. Increasing CT adoption in the SJV would contribute to maintaining soil health and reducing costs of production in a region of high agricultural production.
Long-term Reduced Tillage and Cover Cropping Change Soil Chemical Properties Under Irrigated Mediterranean Conditions

Book Description
Reducing tillage and fallow periods may improve agricultural sustainability, addressing issues such as soil degradation, water and air pollution, and rising energy costs. From 1999 to 2012 we compared conservation (CT) and standard tillage (ST) with (CC) and without (NO) cover crops for a cotton-tomato rotation in a Panoche clay loam soil in Five Points, CA. CT considered a reduction of tractor passes of 50% and 40% for tomato and cotton respectively. Soil samples from 0-15 cm and 15-30 cm were analyzed for total N and C, nitrate, Olsen phosphorus, interchangeable potassium, pH, electrical conductivity, and organic matter. After 13 years of rotation, both conservation tillage and cover cropping increased soil C and N. In CTCC, total C and N increased approximately 19 and 1.1 t ha−1 respectively in the 0- to 30 cm depth. In STNO the C was around 8 t ha−1 higher, while total N was approximately 0.2 t ha−1 lower than in 1999. Electrical conductivity increased in all treatments, primarily in the 15- to 30- cm depth, as a consequence of salts accumulation from irrigation water and fertilizers. The EC at that depth was significantly higher in ST than CT; reaching approximately 1.53 mmhos cm−1 compared to 1.23 mmhos cm−1 in CT. CTCC showed the highest values for extractable P and K. Neither pH nor nitrate content changed significantly in any of the treatments during the duration of the study. Total C, N, P and K were higher in CT and as a result, some agronomical features of the soil were improved. However, these nutrients were concentrated in the surface layer of soil, away from where the vast majority of roots are, which may limit their uptake by crops and thus other mechanisms would be needed to make them available. Under irrigated Mediterranean conditions, both CT and CC appear as feasible alternatives to conventional agriculture. If profitability is maintained, and water constraints are managed, these practices may become increasingly attractive for cotton and tomato farmers in the San Joaquin Valley.
